6.Features.
1. True automatic discharge function, no need to manually discharge.
2. High output power of the instrument, real-time voltage measurement (actual charged voltage of the sample), leakage current measurement, automatic discharge (discharge voltage measurement)
3. Intelligent voice prompt function
After starting up, the voice prompts "Welcome to use the anti-interference insulation resistance tester, please select the appropriate voltage for measurement". After starting, the voice prompts "Do not approach the high voltage danger". After the automatic measurement is completed, the voice prompts "Measurement is over, it is discharging automatically, then the discharge is completed, and the discharge voltage is 0v.
1).Designed in strict accordance with safety standards, output voltage: 500v 1000v, 2500v, 5000v, 10000v.
2).This instrument automatically calibrates the function and automatically calibrates the accuracy before testing.
3).This instrument has the actual test product charging voltage measurement function, leakage current measurement function, automatic discharge function. It can be visually seen through the actual test product charging voltage measurement function whether the drop voltage of the test instrument after the load meets the national requirements. Moreover, the actual test sample charging voltage measurement function and leakage current measurement function can visually see the quality of the sample insulation.
4).It can automatically measure and memorize R15S, R60S and R10min values, and automatically display the polarization index (PI), the induced absorption ratio (DAR) test value and test time.
5).Automatic discharge: The advanced high-voltage discharge technology is used to quickly discharge the capacitive sample. The discharge voltage is measured in real time during discharge (test sample voltage is 0v). For example, the test sample voltage is 10000v, then the discharge is stopped by 10000v when the test is stopped. Go to 0v (real-time visual display) to monitor the discharge voltage in real time, and prompt "safe disconnection", the operator can disconnect the line (for the extra large test sample, after the automatic discharge, please perform manual discharge to remove the line!) .
6).Internal rechargeable lithium battery power supply or AC power supply, the real AC and DC does not affect the test accuracy.
7).Battery power digital display and undervoltage alarm protection.
8).Intelligent battery charging management can effectively prevent battery overcharging.
9).Short circuit protection, the instrument will not be burnt out in the short circuit condition (use the voltage level within 2500V as much as possible in the nuclear phase).6. Related Products.
